Coating VOC testing

Basic introduction

In order to promote energy conservation and environmental protection, with the approval of the State Council, a consumption tax has been levied on coatings with a Volatile Organic Compounds (VOC) content greater than 420g / L under construction from February 1, 2015.
Coating refers to a general term for a class of liquid or solid materials that can be applied to the surface of an object to form a solid coating film with protection, decoration, or special properties.
The Chinese coatings industry defines VOCs as "any organic compound with an initial boiling point below 250 ° C at a standard pressure of 101.3kPa.
